This two floors of the carbureting-chamber, carried may be done by any of'the well-known devices up above the second floor of the chamber high for 'that purpose; but where it is practicable enough to prevent the gasoline on the second to use a flow of water having a considerable floor from flowing down it, th'en'turningdowa' I00 fall we prefer the use ofv it inthearrangement ward to and lying across the second floor as shown in Fig. 2 of the drawings. the pipe a lies on the lower floor, having the perforatedbranches 0/ arranged as on the lower floor.

a is the eduction-pipe through which the carbureted air passes to the burners.

c is a pipe which conducts the gasolinefrom the reservoir, Fig. 1, to and into the tilting pan in the upper part of the carbtn'eting-chamher.

0 is a cock in the pipe 0, which is opened and closed, as the service of the apparatus requires, by the movement of the lever 0 c is a simple lever pivoted and connecting the cock 0 with the movable connecting-rod 0 which extends downward through c, a sleeve or tube, and connects with 0 a float in 0 a chamber on the lower floor of the carburetingchamber, having openings at the bottom to allow it to fill with gasoline from the carbureting-chamber.

c is a tilting pan of oval form, having on one side a weight and on the other side a small supplementary pan, the whole suspended by a rod passing through the longer diameter of the pan and resting at its ends upon supports affixed to the wall of the carbureting-chamber. The weight rests upon astud fixed on the wall of the chamber, supporting the pan in a horizontal position. a is the weight mentioned. 0 is the small supplementary pan mentioned on the side of thepan 0, into which gasoline will flow from the pan 6 when it is filled up to the opening into 0 e is the rod upon which the pan 6 is suspended, passing through the pan in the line of its longest diameter, a little one side of its center line, and resting at its ends in bearings on the wall of the carbureting-chamber loosely, so that it will revolve partially and allow the pan 0 to tilt over and discharge its contents.

g is the water-passage through which a current flows into the air-forcing apparatus, (shown in Fig. 2,) having a nozzle or delivery contracted to a diameter much smaller than that of the water-pipe, discharging the fiow of water through the center of a pipe of larger diameter below, into which, through the opening marked g, air is drawn by the flow of water and forced into 9 an airchamber, having 9 a partition cutting off a part of one side of the air-chamber 9 with openings only at the bottom of the partition, through which the water passes to 9, an opening, through which it escapes.

h is a bed of absorbent material, preferably coarse sawdust. Two of these beds are shown in the drawings, one above the other.

i is a second fioor of the carbureting-chamher, about eighteen inches above the first or lower fioor, supporting the air-pipe a and its distributing-branches and a second bed of absorbent material.

It is a circular metallic plate, of diameter equal to the inside diameter of the carburetingchamber, thickly perforated with fine holes and resting over the bed or absorbent material, and upon which the gasoline flows, and, falling through the perforations, is evenly distributed over the absorbent bed below. There are two shown.

at is a pipe through which the gasoline, when it has risen on the second fioor of the carbureter to the height of about six inches, will flow into the pan 0 below, its lower end being sealed, so that air cannot pass up through it, by carrying it down below the lower pan 0 a distance a little greater than the height of the bend of the air-pipe a? above the second floor, and then turning it up and carrying its discharge-opening over the edge of thelower pan 0 in such manner as not to interfere with its tilting.

The object of the second flooring in the carbureting-chamber, the second set of air-distributing pipes, bed of absorbent, and perforated plate is to increase the carburetin g power of the apparatus, so as to allow the air to be forced through it with much greater rapidity, and thus supply twice as many burners as could be supplied if only one tioor were used. Where but few burners are to be supplied one floor is sufficient.

It is obvious that more than two floors may be placed in one carbureting-chamber by increasing its height, and where a large number of burners are to be supplied three or four floors may be used.

The machine being constructed and set in its place, with all its connections made and the reservoirs for gasoline filled, the cock in the pipe 0 is opened and the gasoline flows into the upper pan 0 until it is filled nearly full, when it flows into and fills the small supplementary pan 0 the weight of which, when filled, will overbalance the weight 0 on the other side of the pan e and tilt it a little, when the body of the gasoline, filling the pan, flows toward the declining side, and the increased weight tilts the pan far enough over to empty its entire contents upon the perforated plate It, spreadingthe fluid over its entire surface. As soon as the gasoline has gone out of the pan 0 the weight 0 instantly brings it back to its position, and it is again filled and again emptied, and so on until the upper bed of absorbent is saturated and the gasoline fills the floor deep enough to fiow through the pipe m. The filling and emptying will continue until the lower bed of absorbent is saturated and the lower floor oi' the carburetin g-chamber filled with the gasoline to the depth of six or eight inches. The gasoline fiowing into the small chamber 0" raises the float c and rod 0 moving the lever 0 closing the cock 0. At this point of progress the air-t'orcin g apparatus is set in motion, and air is driven through the pipe at to and across the lower fioor of the chamber, issuing from the holes in the branch pipes at, is evenly distributed, and rises through the whole body of gasoline on the lower fioor of the chamber and through the body of absorbent material and the perforated plate It into the open space where the lower pan 0 is suspended; thence it enters the air-pipe a and its distributing-branches, rising through the sec- 0nd stratum of gasoline and absorbent material and perforated plate, fills the open space, and passes to the burners through the pipe u When the passage of air through the lower stratum of gasoline has taken up enough of it to lower the float a two or three inches, its descent, acting on the lever 0 opens the cock 0, and the upper pan 0 fills and empties until the float rises again and closes the cock 0.

It is obvious that the air forced through this carbureting-chamber will always be equally and uniformly charged with gasoline vapor while the gasoline-reservoir is kept supplied.

The apparatus may be located in a pit or small brick or stone structure at some distance away from the building to be lighted.

We claim as new and our invention- 1. In achamber for carburetin g air for illuminating purposes, the tilting pan c, having on one side of it a weight, which rests on a stud in the wall of the chamber, and on the other side of it a small supplementary chamber, and

In a carbureting apparatus having two or more floors and chambers and two or'more sets of air-distributing pipes, the bent tubes a and m, in combination with the carbureting chambers, substantially as described, for the purposes stated.
